TRS:

  plus(plus(X,Y),Z) -> plus(X,plus(Y,Z))
  times(X,s(Y)) -> plus(X,times(Y,X))

max/plus interpretations on N:

  plus_A(x1,x2) = max{7, 5, 6}
  plus#_A(x1,x2) = max{1, -1, 2}
  times_A(x1,x2) = max{6, 7, 1 + x2}
  times#_A(x1,x2) = max{0, 3 + x1, -1 + x2}
  s_A(x1) = max{5, 5 + x1}
  s#_A(x1) = max{0, 0}

precedence:

  times > plus = s
